UNITED STATES ERICK KARRIO, OF HANCOCK, MICHIGAN.

RAILWAY SPIKE.

Application filed May 27, 1921.

To all whom it may concern:

Be it known that I, ERICK KARRIO, a citizen of the United States, residing at Hancock, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Railway Spikes of which the following is a specification.

This invention relates to improvements in railway spikes for securing the rails to the ties, and has for one of its objects to improve the construction, and increase the grip of the spike in the tie and cause t to effectually resist any force which would withdraw the spike from the tie or to loosen it therein.

\Vith this and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention:-

Figure 1 is a side elevation of the improved spike embedded in a tie and engaging the adjacent portion of a rail flange, the portions of the tie and flange being in section.

Fig. 2 is a front elevation of the improved spike.

Fig. 3 is a transverse section on the line 3-3 of Fig. 1 enlarged.

The improved spike comprises a stock indicated as a whole at 10 and formed with the usual head 11 overhanging at one side as shown at 12 to bear over the adjacent part of the flange 13 ofa railroad rail. A portion of the tie is represented at 14 with the rail resting thereon.

For the purpose of this description the face of the stock next to the rail is referred to as the front face, the opposite face as the rear face and the remaining faces as the side faces.

The front and rear faces of the stock are tapered toward the tie penetrating end or point, and the terminal of the penetrating end is formed sloping away from the front, as shown at 15.

The front face of the s ike 10 next to the overhanging part of the ead 11 is recessed as shown at 16 to en age over-the outer edge of the flan e 13 of the rail.

Formed in t e front and rear tapered Serial No. 472,976.

faces of the stock are V-shaped grooves 0r recesses 17. The grooves extend for a considerable distance into the body of the spike thereby producing cutting edges and pro ducing pockets or cavities into which the fibers of the tie enter thereby materially increasing the grip of the spike.

Formed in the forward face of the stock next to the flange receiving recess 16 is a longitudinally directed channel 19 with its edges knife or chisel shaped as shown at 20 in Fig. 3.

By this arrangement when the spike is driven into the tie, the sloping point .15 will cause the spike to be forcibly compressed at the upper end toward the rail and likewise cause the knife edges 20 to penetrate the material of the tie and thus materially increase the grip of the spike and render it more secure and not liable to work loose under the jars and concussions of the rolling stock.

The improved device is simple in construction, can be manufactured at no greater expense than any ordinary spike after the dies are produced, and materially increases the efiiciency in the resistance to loosening for removal from the tie.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

What is claimed as new is A rail spike including a stock and an overhangin head, the forward and rear sides of said stock being tapered toward the tie penetrating end and said tie penetrating end sloping away from the overhanging portion of the head, the side of the stock next to the overhanging portion of the head being recessed to provide a seat for the rail flange, and the tapering forward and rear faces of the stock havin V-shaped grooves, with cutting edges, an the portion of the stock next the recess formed with a longitudinally directed channel having tie penetrating edges In testimony whereof, I a x my signature.
